Iris's phone report (docs/IRIS_TODO.md, 2026-09-07 night): the ring held
1339 lines and dropped 4050 more, almost all of it naga::front/wgpu_core/
jni logging at Debug unconditionally, because RingLogger accepted every
target at whatever level `log`'s own max was set to. The trace gate added
in 992c472 only covers iris's own debug! call sites, not a dependency's.
ring_accepts() is the one filter, applied in RingLogger::log rather than
per callsite: Info and above always rings, from anywhere (a dependency's
real warning is worth keeping); Debug and Trace ring only from `iris`/
`client_core` targets, and only while tracing is on. Tracing itself is
`iris::diagnostics::trace_enabled`, passed into RingLogger as a plain
`fn() -> bool` rather than called directly, since client-core sits below
iris and must not depend on it -- the same reason `inner` (the platform
logger) is already injected rather than chosen here.
Also adds LogRing::tail_text and COPY_REPORT_TAIL_LINES (150, named and
reasoned at the constant) for the next commit's Copy report trim.
